js获取本机操作系统类型的两种方法【javascript】

web前端|js教程 关于机器用的操作系统，我们可以随便点击下鼠标就能够获取，但是如何使用javascript获取本机的操作系统类型呢，下面就通过一段代码示例简单介绍一下，希望能够给需要的朋友带来或多或少的帮助。

function GetOSInfo(){  var _pf=navigator.platform;  var appVer=navigator.userAgent;  if(_pf=="Win32" || _pf == "Windows")  {   if(appVer.indexOf("WOW64")>-1)  {    _bit = "64位";   }  else  {    _bit = "32位";   }   if(appVer.indexOf("Windows NT 6.0") > -1 || appVer.indexOf("Windows Vista") > -1)   {    if(_bit=='64位' || appVer.indexOf("Windows Vista") > -1)   {     return 'Windows_vista '+_bit;    }   else   {     return "Unknow1";    }   }  else if(appVer.indexOf("Windows NT 6.1") > -1 || appVer.indexOf("Windows 7") > -1)   {    if(_bit=='32位' || appVer.indexOf("Windows 7") > -1)   {     return 'Windows_7 '+_bit;    }   else   {     return "Unknow";    }   }  else  {    try   {     var _winName = Array('2000','XP','2003');     var _ntNum = appVer.match(/Windows NT 5.\d/i).toString();     return 'Windows_' + _winName[_ntNum.replace(/Windows NT 5.(\d)/i,"$1")]+" "+_bit;    }   catch(e)   {    return 'Windows';   }   }  } else if(_pf == "Mac68K" || _pf == "MacPPC" || _pf == "Macintosh")  {   return "Mac";  } else if(_pf == "X11")  {   return "Unix";  } else if(String(_pf).indexOf("Linux") > -1)  {   return "Linux";  } else {   return "Unknow";  } }

第二种方法：

-1);   if (isLinux) return "Linux";   if (isWin) {     var isWin2K = sUserAgent.indexOf("Windows NT 5.0") > -1 || sUserAgent.indexOf("Windows 2000") > -1;     if (isWin2K) return "Win2000";     var isWinXP = sUserAgent.indexOf("Windows NT 5.1") > -1 || sUserAgent.indexOf("Windows XP") > -1;     if (isWinXP) return "WinXP";     var isWin2003 = sUserAgent.indexOf("Windows NT 5.2") > -1 || sUserAgent.indexOf("Windows 2003") > -1;     if (isWin2003) return "Win2003";     var isWin2003 = sUserAgent.indexOf("Windows NT 6.0") > -1 || sUserAgent.indexOf("Windows Vista") > -1;     if (isWin2003) return "WinVista";     var isWin2003 = sUserAgent.indexOf("Windows NT 6.1") > -1 || sUserAgent.indexOf("Windows 7") > -1;     if (isWin2003) return "Win7";   }   return "None"; } function locationHref(e){ switch(e){ case 'Mac': window.location.href='http://www.baidu.com'; break; case 'Unix': window.location.href='http://tieba.baidu.com'; break; case 'Linux': window.location.href='http://map.baidu.com'; break; case 'Win2000': window.location.href='http://mp3.baidu.com'; break; case 'WinXP': window.location.href='http://baike.baidu.com'; break; case 'Win2003': window.location.href='http://zhidao.baidu.com'; break; case 'WinVista': window.location.href='http://hi.baidu.com'; break; case 'Win7': window.location.href='http://video.baidu.com'; break; default : window.location.href='http://www.hao123.com/'; break; } }" _ue_custom_node_="true">
